T all whom it may concern.-

The interior mechanism is surrounded by a box or casing B, havingfeatures of construe.- tion and arrangement which will be describedbelow.

B" is a cross plate or frame supported in the front side the motormechanisms for marking time and for actuating the recording devices,together with the intermediate controlling vmain frame and adapted tosupport upon its l i means or releasing and stopping devices by whichthe primary motor at `predetermined intervals permits the secondarymotor to operate; but inasmuch as there are now several well-knownvforms of clock-movements or equivalent motors and intermediateregulating or controlling devices adapted for this purpose, any one ofwhich can be employed for attaining the purposes more particularlycharacterizing the present improvement, it. will not be necessary toherein illustrate or describe in detail such parts.

It is suiiicient to say that the main powershaft C is actuated atpredetermined intervals by the secondary motor (of whatever sortselected) when released by the controlling devices, which are moved bythe primary motor. For the purposes of illustrating Ihave constructedand related the parts of the present mechanism in such way that therecording devices shall be actuated by the primary motor and thecontrolling means.

Within the casing there is a frame for supporting the various parts ofthe recording mechanism.

A is a top bar and A is a bottom bar secured by brackets to the casingor outer frame. At the front end of the recording-chamber there is avertical bar or plate A2, and at or near the rear end there is anotherplate, A3. A4 isla central longitudinal bar or plate connecting theparts A2 A3. A0 A are an upper series of bars or plates between those atA and A, and A7 A7 are a lower kseries of similar bars or plates betweenthose at A' and A. By examining Figs. 7, 8, and 9 in connection withFig. 3 the several features of construction and arrangement of thesebars or plates will be understood. They are provided with lapertures orwith bearings for the shafts and rods which supportthe recordingdevices, the inking-frames, &c.

The front wall of the casinghas a top bar A", preferably formed of metaland of the shape shown in Fig. 10. It supports a series of locks andmechanisms by which the operatives can start or stop their respectiverecording devices. It is formed with apertures at aw to serve askeyholes and on the front side has a groove or passage-way a to receivethe device which intermittingly closes andopens the keyholes, to bebelow described. It also has a groove or chamber at as to hold theseries of indicators. At a it has an elongated aperture through whichconnection is made between the sliding keyhole-closer and the leverwhich operates the latter, to be described.

In the mechanism shown there are two series-an upper and a lower`ofrecording devices and for the lower there is a bar A1", which supports aseries of locks and other devices and is constructed and arranged substantially as is the bar A,just described. Upon the front sides of thesebars A9 A10 thereare secured face-plates A, which are provided withkeyholes, as shown in Fig. 1. -Behind the bars A9 A10 there are insideplates A", (see Figs. l2, 5, and 6,) which are provided with .D at everyhalf -hour.

bearings or supporting devices for some of the interior parts.

C is a shaft which receives power from the clock or motor situated inthe chamber on the front side of plate B. Through gears C' and C2 itdrives a shaft D, arranged longitudinally in t e recording-chamber andmounted in the aforesaid plates A, A, and A6. A small fraction of arevolution is imparted to shaft It is provided with one or morerecording-wheels E E'IL2 E3, ac. Any number can be arranged upon theshaft, limited only by the power of the driving-motor. As each of theserecording-wheels and its controlling parts and other adjuncts aresubstantially a duplicate of the others, a description of one, such asthat at E, will be sufficient. This wheel E is mounted loosely on theshaft D, it being formed with a hub part e, (see Fig. 16,) a web e', anda periphery at e, it being chambered out, as at e". The peripheralportion is formed with a flange or lip e* and with a rabbet at et'.

E5 is a ring which fits in the rabbet er and is formed with a flange e,which is' similar in to that at e.

The ring EB is secured and adjusted in the rabbet er by means of screwsat e7.

F, Fig. 39, indicates a type-strip adapted to be placed in the groove orspace between the flanges e* and e6. This type-strip is formed of metaland upon its exterior face has one or more series of type. Preferablythere are two series-one indicating periods of time .and the otherindicating tbe corresponding amounts of money respectively earned by anoperative at the ends of each of such periods of time successively. Asaforesaichthe machine illustrated is adapted for making halfhourrecords. In such case each of the type bands or rings F is formed with aseries of numeral-types f, commencing with and continuing with 1, 11%,2, 225, &c. As different operatives are paid different wages, the typebands or rings vary fromv each other with respect to the wage-type.

In Fig. 39 a series of type is shown at f to indicate the amounts earnedby an operative who is paid twelve cents per hour, the first charactersin the series being .06, followed by .12, .18, .24, &c.

In Fig. 39L an arrangement of type is shown such as can be practicallyused for indicating amounts of wages based on twelve and onehall centsan hour, the series here commencing with ".06, followed by .12, .19,.25, .31, .38, &c.

In Fig. 39b a series is shown in which the basis is twenty cents anhour, in which case it commences with 10, followed by .20, ".30, &c.

In all of the figures it will be seen that the characters which indicatethe time are the same. In other words, all of the type bands vor ringscan bealike in length and width and IOO IOS

IIO

'it has been printed bya' typeband of the character of that'in Fig. 39.These type rings or bands are readily detachable from and secured to`their respective wheels. To put one in the proper place, the screws e7,Fig. 16, of its wheel E are loosened to permit thering I E5 to be drawnaway slightly, and thereafter the type-ring Fds laid against theperiphery e2 of the wheel and of the ring, and then the screws e7 areagain drawn. up. The result is to tightly clamp the band in place. Toadditionally secure it, the inner edges of the anges e* and e arebeveled and the edges ofthe typeband are correspondingly shaped, asshown in Fig. .16.Y To insure that the band shall be placed properlywith relation to the axis,-I provide the periphery e2 with a pin es,Fig. 24, and form an aperture f 3 in the band F. When aband is to beapplied, it is so placed that the aperture ffits over thepin es. Theperforated end of the band is thus held in proper position, and theother end is carried around the wheel and brought into contact with theend near 'the perforation to make a perfectly complete circle. The metalofthe band may be of any of the sorts -used in typographical work, andas these metals are generally more or less flexible the bands can beeasily cast in straight forms and can be subsequently bent to a circularcurve, so' that they can be readily applied to 'or withdrawn from awheel without breakage.

As above said, the Wheels are each loose on the shaft D; but at any timethe operative can clutch or connect the Wheel tothe shaft as follows,other parts of the mechanism permitting:

At G G there are locks supported, as aforesaid,in the ba'r A. Each ofthese locks may as to its details be of any preferred form, though I- atpresent employ those of the class known as Yale locks. When the properkey G', Fig. 41, is inserted, it can after passing the tumblers engagewith and rock a' shaft g,

' which is mounted in the inside plate As and is provided with acrank-head g', having a pin g3, Fig. 37. The latter engages with a leverL, carried by a rock-shaft H, Fig. 6. This y shaft is mounted inabearing vat hin the said "plate A8 and in a bearing at It on the centralframe. 'Its inner end has a shipping-fork H', which'engages withthegrooved hub i, Fig.

34, of a'sliding collar I, loose on shaft D. Collar I is adapted toaetuate a friction-clutch J, situated in, chamber e3-in type-wheel E.The clutch has a hub j, secured to shaft D, radial bars j', and splitringJ. The ring is divided at jf into two parts, each part having an endrigid with the bars 77 the other end being free.

J2 J 2 are levers pivoted at y" j* to bars j'. The short arms f5 haveprojections js arranged to'bear against the loose ends of theclutchring. The sliding collar I is beveled at z", Fig. 19, and whenmoved inward by the parts at H and H' through the operatives key thecollar engages with the levers J2, separates them, and forces themoutward, as will be seen by comparing Figs; 35 and 36, the result beinglthat the levers, through the parts at f3, force the loose ends of thefriction-ring outward a short distance and against the inner wall of theperiphery e2 of the type-wheel.

`The mnutest fraction of an inch of such outward movement is all that isnecessary. In this way a delicately-controllable, but instantly andpositive acting, friction engagement can be produced between the ringand the typewheel.

Preferably the sliding collar I is formed with a hardened surface toengage with the levers, and the levers J2 are provided with hard-steeladjusting-screws J 3, adapted to durably resist the wearing action ofthe clutchcollar I, by means of .which a delicate adjustment can besecured and maintained, so that the throw of the leversand of thefrictionring can be regulated with the utmost nicety. By means of thesedevices it is possible for an operative to at any instant starthistypewheel and to as quickly throw it out of action.

The inking. paper-feeding, and paper-guiding devices are constructed andarranged as follows:

K`indicates a rock-shaft mounted in the front part of the frame-platesA2, A3, and A6. To this are secured a series of frames L, each vhavinga' hubZ and -plates l', Figs. 23 and 25. l

At K2 there are slots for the platen and at k3 slots for theinking-roll. The platen consists of a roller L and a shaft l, whose endsextend through the slots K2. The roller is formed of atubular core withaflexible jacket, as of rubber, the core or tube fitting loosely butsnugly to the shaft Z. This insures that the roll shall have the utmostfreedom in rotation and yet be held firmly and uniformly across thetype. The shaft Z* is carried by a lguide or frame having the side barsZ5, Fig. 28, and the cross-plate Z2.

Z3 is a coiled spring held bya suitable pin and pressing against theplaten-frame and normally tending to force the platen-roller toward thetype-wheel. This frame also assists in holding the platen uniformlyacross the entire periphery of the type-Wheel.

M indicates the inking-roller. It is carried by a shaft m10, whose endslie-in the slots k3. It is pressed outwardly by a frame having the barsm' and the cross-bar m2, against Which the spring m3 bears. Springs m*are placed adjacent to the ends of the shaft mw and are so shaped as tohold the inking-roller in line and prevent its escaping from the slots.This inking-roller is peculiarly constructed. It comprises the saidshaft mw, a cylinder or drum IOO IIO

mfland the heads m5 m6. The head m is preferably detachable, beingadapted to engage with a thread at m7, by which it can be screwed'tightly against the cylinder m14 At m8 there are ink-passages.

m0 is a pad or jacket surrounding and fastened to the cylinder and madeof material capable of absorbing, hold-ing, and transmitting the desiredamount of ink. The cylinder is charged with ink after removing the headm6. The ink used is preferably one of the sorts employed by printers.After the head is replaced the ink can escape only outwardly through thepad.

I employ a novel form of pad.A (Conventionally shown in section in Fig.32.) It consists of a tape or band of thin linen or suitablel wovenfabric, which is spirally wound in suer osed coils commencin at m15 andtermil I 5 nating at m1 on the surface, where by fine threads it isstitched fast. I have found that an inking-roller of this character willcarry a suHicient quantity of ink tojanswer for a long period and willfeed and deliver it uniformly in a superior manner. The supplybeingcontained on the inside, there is an effectual overcoming of thedifficulty incident to and experienced with those inking-rollers whichare supplied from the outside. In the present case there is always anassurance of a fresh supply of moist ink, and there is no troubleexperienced from its drying or hardening upon the exterior surface ofthe pad or roller. Byl

forming the pad in the Way described I can vary thefeed within closelimits to meet any requirements as to proper delivery.

The inking-frames L hold their respective paper tapes against thetype-wheels, and when the latter are in motion the tapes are advanced bythe 'pressure of the wheels. When an operative throws out his clutch,its Wheel andtape remain stationary under the pressure exerted by thesprings m3 and Z3. It will be seen that the inking-roller is below theline which joins the axes of shafts D and K and that the platen is abovesaid line and that consequently the type-wheel E is firmly locked frommovement in either direction so long as the platen and inking-roller arepressed against it.

The paper is supported on spools N, carried in the hangers at N2 on theframe-pieces A2, A, and A". Each tape N passes upward from the reel orspool over a guide-roller behind the inking-roller and thence betweenthe platen and the type-wheel and thence downward to any desired place.Preferably the loose ends of the tapes are allowed to drop into thechamber in the lower part of the casing, as shown in Fig. 40.

The fact that the type-wheel of any operative is clutched to the shaftor is disengaged ltherefrom is disclosed by an indicator constructed andoperated as follows: The aforesaid crank-head g' immediately behind thetime.

lock and rocked by the operativeis lrey has a 6 5` second crank-pin g2,Fig. 6. This engages with the lever o, which is secured to a rockshaftV. The latter is mounted in the apertures o' in the plate A8 and o2 inthev bar A. At its outer end shaft Vis ,connected to an index-plate V',lying in the aforesaid chamber a8 in the bar A. This index-plate V' isprovided with characters, such as the words lon and offone for showingthat the clutch and the type-Wheel have been engaged and the other forshowing that they have been separated, for it will be `understood thatwhen 'the shaft g turns lever H to move the clutch it simultaneouslymoves the parts at lv, V, and V'. W is a sliding bar or plate forclosing the keyholes except at predetermined times. It is showndetachedin Fig. 42, in dotted lines in Fig; 1, and in vertical section in Fig.6. It fits in the aforesaid groove or passage at a9 in the bar Aimmediatelyvv behind the face-plate All. It is connected with a leverW', Fig. 44, in or near the clock-chamber and adapted to be actuated atproper times by any suitable mechanism controlled by the clock. It isprovided with apertures w, and when thelever W' moves it these aperturesare brought to regis-l ter with the keyholes of the locks at G. They areheld in such registering position for a minute or two at the desiredtimes, and whenl so held the operatives can have access to theirrespective locks'.

The method of using the mechanism above described will be readilyunderstood by those acquainted with the art to which it appertains. Theseveral operatives have control independently of each other and of otherparties of the stopping and the starting of their respective wheels. Forinstance, if they are paid by the week and it is assumed that the wheelsstart their actions on Monday morning, that operative or thoseoperatives who have been present from the commencement to the end ofeach period of working hours will at the end of the week have indicatedupon their respective tapes the sum-total of, all the half-hours duringwhich they have been engaged and also the sum-total of the wages due forsuch If any operative has fallen short of the full number of-workinghalf-hours, it will be indicated by his tape, and acorrepondingly-reduced amount of wages will be shown to be due. At theend of the week or other time fixed upon as the pay period the.timekeeper opens the door of the casing and throws back all of theinking-frames. He then' tears off or examines each of the several tapesand is able to instantly ascertain the time-of andthe Wages due to theoperative.

The throwing back of the inkingframes just referred to can beaccomplished as follaws: The shafts K and K', which support the several:series of inking-frames, can be rocked-,as shown in Fig. 40, and theythen IOC move the said' frames upward and carry the platens andinking-rollers away from the typewheels.

In Figs, 6 and 40, S and S are gear-segments secured to the rock-shaftsK K. S2 is a wheel engaging with these segments and having a crank S3connected to it. T 'is a link extending from the crank S3 to a hinge ton the door U, which closes the front side of the bottom part of thechamber. at u, and when it is opened it pushes the lever T upward, andthe latter rocks wheel S2, segments S S', shafts K K', andprinting-frames L, and said frames assume the position shown in Fig. 40.n

4 At such time--namely, when the timekeeper opens the door U-the papertapes are relieved f rom` pressure against the type-wheel, and thereforethe timekeeper can tear ofl, if he desires, the tape at 'a line back ofthe last printed character and provide a clean place for the nextprinting to commence.

Under some circumstances I do not connect the door U to the deviceswhich move the inking-frames. I allow it to be opened independentlythereof and provide a lever or equivalent supplemental to the door bywhich they can be moved at will. This is done when it is desired to havethe mechanism so arranged that access can be had to some individual tapewithout affecting the others. For instance, if during the'week it isdesired to ascertain how much is due to some employee and to eX- aminehis record separately while the others continue in their normalmovements it is not desirable to affect the other printing mechanisms inthe way described above. In such case the tape of the employee inquestion is released by drawing the platen-roller back and drawing thepaper away from the wheel, the pressure of the ink-roller in themeantime being 'sufcient 'to prevent any movement of the type-wheel.

It is necessary at times to return the typewheels to theirzero-points-say, for instance, on or before each Monday morning. Anysuitable retracting mechanism can be used. That shown consists ofweights O, one for each wheel. The weight is attached to a cord 0, whichextends vover one or more sheaves 0' and has its end connected to thehubof the typewheel. y As soon as the pressure of the inking-roll andplaten is removed from the wheel,

as it is when they are in the position shown in Fig. 40, the weight willturn the wheel back to zero-point, assuming that the clutch isdisengaged. Hence when the printingframes are thrown up, whether bymovement of the door U or otherwise, the wheels are returned. To stopthem accurately at the zeropoints, pins 02 are used, which strike thestops 0a on the frame.

As above stated, it is unnecessary to herein describe or illustrate indetail any particular form of clock or motor, either primary or The dooris hinged y secondary. I prefer to employ motors and controlling devicesof the sort used in what 1s now known as the Peler recorder, such as isillustrated and described in Patent No.

547,156, and in Figs. 43 and 44 I have illustrated the general featuresof such a motor, and in Figs; 43 and 44 I have illustrated more indetail such a motor mechanism as is conventionally illustrated in dottedlines in Fig. 2, as aforesaid. Referring particularly to the last saidfigures, it will be seenthat the prime motor is a simple clock mechanism4comprising a spring-barrel z and a train of gears z', a2, and z3 fortransmitting motion from said spring-drum to the shaftzi, on which thehands are mounted, there being the usual regulating-gearing at Z. On thesaid shaft ai* there is secured a cam z5, adapted to contact with oneend of the lever zz, and the other end of said lever is adapted toengage with laterally-projecting pins m5 on a disk mi, forming part ofthe secondary motor, (indicated as a whole by X2.) When the cam z5releases the lever a" from the secondary motor, the latter is allowed tomove and impart movement to the shaft C, which drives the recordingdevices until the next succeeding pin or stud m5 comes into contact withthe lever and again holds the secondary motor stationary.

W. indicates a gear-wheel or disk which is geared to the prime motor andadapted to revolve once in twenty-four hours. On one .face this disk isprovided with a series of projecting cam-studs Q04, corresponding innumber to the times which it is desired to move the slides W to uncoverthe locks Gr, and said cam-studs are adapted to contact with a cam w3,carried by a lever W3, the free end of which projects under a finger wz,projecting from the lever W' at its fulcrum. By this arrangement ofparts it will be seen that the lever W will be rocked and the slides Wmoved whenever one ofthe cams w4 causes the lever W3 to rock upward atits free end. The slides W and lever W are normally maintained in thepositions indicated in Figs. 1 and 44 by a spring w. However, as statedabove, any suitable mechanism by which the driving-shaft will beintermittingly actuated and the slide W will be moved to uncover thelocks G at predetermined intervals of time while the powershaft and'recording devices are held against IOO IIO

engaging parts, or Where a pin is used on one clutch member and a seriesof pin-holes on the other these holes must be very numerous and veryaccurately disposed. Unless there are such numerous teeth or numerousholesl there is no assurance that the two clutch members will cometogether on lines of engagement. For instance, where a pin and a seriesof holes are used there is no assurance that the pin will move exactlyon the line of either of the holes. If it strikes the opposing clutchmember on a line at either side of one of the holes, it will fail toengage. If it should'partially enter one of the holes, but be out ofproper alinement therewith, it will move the type- Wheel. in onedirection or the other undesirably. vOne peculiar difference incident tothis mechanism in contrast with the numerous others which containfriction-clutches is that at the time the clutch is being engaged boththe driving member and the driven one are standing still, whereas inordinary clutch mechanism one of the clutch members is constantlyrotating. In other words, in time-recording mechanisms of the classincluding that herein a friction-clutch has novel and peculiar featuresincident to it, this being the only place to my knowledge where it isabsolutely essential to edect an engagement between the two memberswhile they are both stationary and have such engagement assured beforeeither commences to move, so that it will be absolutely necessary forboth to move at the instant when either starts.

The type-bars F are made cheaply and rapidly by setting in a narrow formordinary type presenting the desired characters. vA matrix is thenobtained therefrom' in any of the now well-known 'ways Uponsuch matrixthe meta] for the band F is placed when in proper condition. Afterhardening it is -withdrawn and its edges are trimmed and shaped. It isthen bent into the circular form and is ready to be applied to thewheel.

I do not claim the combination, with a recordingI mechanism adapted tobe controlled through a lock and a motor adapted to intermittinglyactuate said recording mechanism, of a slide-.bar adapted to preventaccess to the lock controlling the recording mechanism and meanscontrolled by the motor for Withdrawing said slide at predeterminedintervals of time and while the recording devicesare stationary, as Ibelieve that to be the invention of Charles Korfhage; but there arecertain advantages incident to the particular construction andarrangement of parts. herein illustrated and described by which theabove-de scribed operations are carried on.

What Iclalm 1s- 1. In a time-recording mechanism, thecoml bination of apower-shaft, a motor adapted to intermittingly rotate said shaft, arecordingwheel loosely mounted on the shaft, a casing surrounding saidshaft and wheel, a frictionclutch interposed betweenl said wheel andshaft, a lock G supported by the inclosing casing, operating devicescontrolled by said lock, a stop for preventing access to the lock, andconnections between said stop and the motor whereby the stop will beautomatically withdrawn at predetermined intervals of vtime while thepower-shaft and recording-wheel are stationary, substantially as setforth.
